elasticsearch-dsl

The mapping of my Elastic search looks like below: { "settings": { "index": { "number_of_shards": "5", "number_of_replicas": "1" } }, "mappings": { "node": { "properties": { "field1": { "type": "keyword" }, "field2": { "type": "keyword" }, "query": { "properties": { "regexp": { "properties": { "field1": { "type": "keyword" }, "field2": { "type": "keyword" } } } } } } } } } Problem is : I am forming ES queries using elasticsearch_dsl Q(). It works perfectly fine in most of the cases when my query contains any complex regexp. But it totally fails if it contains regexp character '!' in it. It

I am using elasticsearch-dsl for my python application to query elastic search. To debug what query is actually getting generated by elasticsearch-dsl library, I am unable to log or print the final query that goes to elasticsearch.

The output I need will be: { "title" : "Title 1", "books": [{ "book_title": "b title 1", "year": 2014 }] } When I use a nested filter I get all the nested objects even if they don't match. How can I fetch only the matched nested objects? You need to use the nested inner_hits feature like below. { "_source": [ "title" ], "query
